Generally speaking, a single mutation in an existing gene cannot produce a new gene with a different function.

일반적으로 말해서, 기존 유전자의 단일 돌연변이는 다른 기능을 가진 새로운 유전자를 생산할 수 없다. 

 

If two genes differ by only a single base pair, then a single point mutation could convert one into another.

만약 두 유전자가 다른 것이 단 하나의 염기쌍이라면, 그러면 단일 점 돌연변이가 한 유전자를 다른 유전자로 전환할 수 있을 것이다. 

 

Usually, however, these two genes will be regarded merely as variants of the same gene, and will have an identical function unless the mutation is at some critical spot that makes the second gene non-functional.

하지만 보통 이 두 유전자는 단지 똑같은 유전자의 변종으로 여겨질 것이고, 돌연변이가 두 번째 유전자가 기능을 발휘하지 못하게 만드는 어떤 결정적인 지점에 있지 않으면 동일한 기능을 가질 것이다. 

 

The same goes for other basic alterations, such as the deletion or repetition of an existing sequence.

기존 (유전자 배열) 순서의 결실(缺失)이나 반복과 같은 다른 염기성 변형도 마찬가지다. 

 

To get a gene with an entirely new function usually requires many, many alterations, a concatenation of several unlikely steps — a series of just the right mutations happening either all at once, or one after another.

완전히 새로운 기능을 가진 유전자를 얻기 위해서는 몇 가지 있을 것 같지 않은 연속된 단계인, 매우 많은 변형 즉 동시에 혹은 연이어 발생 하는 일련의 꼭 맞는 돌연변이가 보통 필요하다.

 

Unlikelihood multiplies into impossibility.

가망성이 없는 것이 늘어나면 불가능이 된다. 

 

If I guess the next card you draw from the deck, you’d be impressed but not amazed.

만약 여러분이 한 벌의 카드에서 뽑는 다음 카드를 내가 추측하면, 여러분은 깊은 인상을 받지만 놀라지는 않을 것이다. 

 

If I guessed ten in a row, you’d suspect a trick because that would happen only about once every fifty quadrillion trials. 만약 내가 연속해서 10개를 추측하면, 여러분은 그것이 5경(京)의 시도마다 대략 한 번만 일어날 것이기 때문에 속임수를 의심할 것이다.
